Training mode is a general idea created by Aca soccer. It is a new game mode for Head Soccer. Training mode is mostly used for 2 things: upgrading your characters and testing new characters without unlocking them. When you enter the Training mode, it will look the same as the Arcade, but all characters,even those you need to pay for real money, and opponents will be unlocked. You also don't need to pay for match with Asura or Pluto, but of course you can not unlock them in this mode. All characters you have unlocked for other modes will have green circle around them where you choose character to play, and all characters you did not unlock will have red circle,but you can use them in training mode. First main thing about this mode is that, when update is out, you can use new characters here
